explain_popen_or_die(3)

✨ NAME ✨

explain_popen_or_die — process I/O and report errors 💖 like it's literally the whole job bestie

---

🌸 SYNOPSIS 🌸

#include <libexplain/popen.h>
FILE *explain_popen_or_die(const char *command, const char *flags);

---

💅 DESCRIPTION 💅

okay so explain_popen_or_die is the function you call when you want to call the popen(3) system call, but you also want it to tell you what went wrong if it goes wrong. bestie behavior honestly. 🫶

If it fails? An explanation gets printed to stderr, grabbed from explain_popen(3), and then the process terminates by calling exit(EXIT_FAILURE). No cap, it just ends it right there. 💀

This function is meant to be used in a fashion similar to this example — the way that it just slots in like that, iconic:

FILE *fp = explain_popen_or_die(command, flags);

• command — the command, exactly as to be passed to the popen(3) system call. exactly. don't get cute with it. ✨
• flags — the flags, exactly as to be passed to the popen(3) system call. same energy, verbatim. 🎀

Returns:

This function only returns on success — see popen(3) for more information. On failure, it prints an explanation and exits. so like, if you get a return value at all, that's the good timeline. 🌈
